Re: Free42 Version 3

I think that Free42 should now be renamed Free42s, where the "s" suffix stands for "supercharged."

Re: Free42 Version 3

The dynamic stack feature is great for the Free42 emulator, but it is even better on the DM42 with its multi-line display. This is why I urge the SM crew to update the DM42 with the new version 3 of Free42, even it there are no current updates for the DMCP OS or other DM42 features and bug fixes. I...

Re: m48 is back as iHP48 (much improved)

Thanks ! Apparently, it can also be configured to emulate the HP 49g+, but I chose to keep it as the HP 48GX. My physical calculator is an HP 48SX.

Yeah, that's much better than on my 25" FHD monitor in Chrome. I also made the same mistake and first though you had 1/3 instead of sqrt(3).

Re: third root of -8...

Both -2 and 1+i sqrt(3) are valid roots. In fact, there are three valid roots, the third being 1-i sqrt(3). If you look at this in polar form, you see that all three numbers have the same magnitude of 2, and with phase angles of 0, 60 and -60 degrees respectively. So, in reality, the calculator is g...

I was a Teenager when I bought my HP41CV. At first there was no money left for the Math Pac.
I'm amazed that you could even afford an HP41CV at that time ! I was 26 when I bought my HP35, and it cost nearly half a month's net take home salary. :shock:

Re: 15 - HYP - Hyperbolic functions

Actually, hyperbolic functions are included as part of the Math Pac module that is included with the DM41X. Also, I prefer to assign them to the SIN, COS, TAN keys in User (USR) mode.
